Q3/ A three - throw cranks shaft has double webbed cranks of 150 mm radius set at 120° to each other and equally spaced with a pitch of 500 mm. the rotating masses at crank radius are: No. 1, 30 kg ; No. 2, 40 kg ; No.3, 40 kg. Balance is to be effected by a balance mass attached to the outside web of crank No.1, with a cntre of mass 150 mm from the central plane of the crank and a radius of 225 mm from the centre of the shaft; and also by removing material, at a radius of 750 mm, from a wheel fixed 750 mm beyond the central plane of crank No.3. Determine the masses to be fitted and removed and their angular positions relative to crank No.1.

Problem #2) The thin plate ABCD has mass 10kg and is held stationary in the position shown (p= 30°) by a wire BH and the two massless parallel links AF and DE. At t = 0sec, the wire is cut and the plate is released from rest; it immediately moves in a pure translation motion due to the system's geometric constraint by the links. Find the forces in each link immediately after the wire is cut. All dimensions are in millimeters. 150 A D -500 H B IC T 200
Derive the equation of motion for the following system, using (the rotation of the beam about the hinge) as the degree-of-freedom. Not that there is an applied force (Fo sin wt) as well as an applied moment (Mo sin wt). The total bar mass is m. Treat the bar as two bars: one to the left of the hinge point; one to the right. The one to the left has a mass moment of inertia of- mL²; the one to the 27 192 1 mL². Then transform this Fo sin cor right has a mass moment of inertia of- 192 differential equation of the Laplace domain, assuming zero initial conditions. Lastly, compute the damping ratio and damped natural frequency for this system. TET 4 fm o Mo sin or
